我有一个产品模型,其中有一个用于产品编号的文本输入字段。在我的Laravel应用程序中,我验证此字段对于该特定用户而言是唯一的。因此,两个用户可以具有相同的产品编号,但一个用户不能重复。到目前为止,验证规则在添加新产品时有效:
'product_no' => 'nullable|unique:products,product_no,NULL,id,user_id,' . auth()->user()->id
但是,当编辑同一产品时,验证失败。可能是因为它已经存在。我不确定如何在验证中排除现有ID。有什么想法吗?
答案 0 :(得分:0)
根据要求的示例
require(igraph)
require(ggplot2)
require(reshape2)
g <- make_star(5)
gAdjMatrix <- as.matrix(as_adj(g))
print(gAdjMatrix)
logMatrix <- (gAdjMatrix == 1)
logMatrix
mm <- logMatrix
mm %>%
melt() %>%
ggplot(aes(Var2, Var1)) +
geom_tile(aes(fill = value,
color = value)) +
coord_equal() +
scale_fill_manual(values = c("black", "white")) +
scale_color_manual(values = c("white", "black")) +
theme_bw() +
theme(axis.title = element_blank(),
axis.text = element_blank(),
axis.ticks = element_blank(),
panel.grid = element_blank()) +
guides(fill = FALSE, color = FALSE) +
scale_x_discrete(expand = c(0,0)) +
scale_y_discrete(expand = c(0,0))
然后具有唯一性的那个就这样
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest;
class Request1 extends FormRequest
{
private $rules;
/**
* Determine if the user is authorized to make this request.
*
* @return bool
*/
public function authorize()
{
return true;
}
public function __construct()
{
parent::__construct();
$this->rules = [
'password' => [
'nullable',
]
];
}
/**
* Get the validation rules that apply to the request.
*
* @return array
*/
public function rules()
{
return $this->rules;
}
}
